90493m is right on an absolute level. The Viva Aurora (25K) will drive them (20 watts I believe), kind of like building a 500K home in a 100K neighborhood. I know this isn't the answer you are looking for but in answer to your question, yes. In the real world you better look for a 80-100 watt push pull tube amp that will work with the impedance dip of those speakers (VTL ST-80's monoblocks, ARC VT100, etc.)if you must have tubes.
Single-ended amps with Martin Logans
I own a pair of Aerius Martins and want to go for the singled ended amps has anyone out there tried this combo? I am considering Audio Electronics AE-1 Signature ( 5 watts ) or perhaps a Bottlehead ( 3.5 watts) Any other advice? I did listen to the new Klipsh and they sound great but really don't want to part with my Aerius at the same time I thik the sound would be better that my Aerius with my Rogue 88 that I'm using.
